CUPBOARD-LATCH.

SPECIFICATION forming part of Letters Patent No. 333,6 6, dated January5, 1886.

Application filed March 30, 1885. Serial No. 160,589. (ModeL) .To aZZwhom it may concern.-

Be it known that we, FRANK WV. MIX and Answer ARENS, both citizens ofthe United States, residing at New Britain. in the county of Hartfordand State of Connecticut, have invented certain new and usefulImprovements in Cupboard-Latches, of which the following is aspecification.

In the accompanying drawings, Figure 1 is a front elevation of our latchand its keeper. Fig. 2 is a rear elevation of said latch with the rearplate removed, and Fig. 3 isa horizontal section on line :0 m of Fig. 1.

A designates the latch-case, and B the keeper. The latch consists of anangle-lever having two radial arms, a and b, with trunnions c cprojecting from each side at the angle or apex of said arms, by means ofwhich trunnions and recesses in the case A the latch is pivoted tooscillate within the case. A rear plate, C, is placed over the latch tohold it within the case. The end of the arm a has a concentric face,which engages the keeper B, while the tail of the arm b lies between twoedgewise-acting cams or inclines, d d, at the inner end of the knob orbutton-turnf, so that by turning the knob or button-turn in eitherdirection the tail of the arm b will be thrown toward the rear of thecase, and thereby the arm a will be withdrawn from the keeper into thecase. A feather-spring, g, is secured within the case, with one endresting upon the inner side of the arm a of the latch to return saidlatch and knob to their normal position when the knob is released.

IVe are aware that latches have heretofore been made with a like knob orbuttonturn, having edgewise-bearing cams on its inner end, in connectionwith a peculiar form of latch having a concentric face for engaging thekeeper, but instead of two radial arms comparatively straight, the latchconsisted of only one crooked arm. The retaining-spring was a spiralone, and had one end rest under this crooked latch, while its oppositeend rested upon the rear plate.

By our improvements the construction is much more simple and the partscan be assembled much more conveniently, and therefore the latch can beproduced at a less cost.

We claim as our invention- The herein-described latch,consisting of thekeeper B, the case A, the two radial arms a I), having trunnions c 0 attheir junction, said trunnions having their hearing in recesses in thecase, the spring g,having one end secured to said case A and itsopposite end bearing upon the inner side of the arm a, and mechanismacting upon the arm I) for throwing the latch, substantially asdescribed, and for the purpose specified.
